Hi all. since several days , ARC does not stream due to communication problems. Only ARC encounters problems with ARC. Roon server runs on windows 11 nuc , phone is Android. Server connection test shows no issues. Thank you trying to solve this issue.Regards Chris

Same issue here.

Why isn’t Roon support responding? I feel completely abandoned as a customer. I’m so glad I haven’t bought a long-term license yet.

They have responded - Roon Labs and Qobuz are working the issue, but clearly they haven’t found either the cause or a fix for it as yet.

The development team should also note that here in Germany, streaming from Qobuz via Roon Arc does not work—at least not on the Congstar mobile network.
Local audio files from the Roon server stream just fine. Furthermore, Roon Arc works without any issues on my local network.
However, I already reported this—albeit not in quite as much detail—7 days ago.

As I said yesterday: Roon Labs and Qobuz are working the issue, but clearly they haven’t found either the cause or a fix for it as yet.

Comme je l’ai dit hier : Roon Labs et Qobuz travaillent sur le problème, mais il est clair qu’ils n’ont pour l’instant trouvé ni la cause ni une solution.

All of a sudden, I can play from Qobuz via Arc! Thanks for looking into this!

It’s still broken here (Cologne-Bonn region, Germany).

Hi! What’s not quite right with Roon?

· Can’t reach my Server, remotes or ARC

Can’t connect to my Server, remotes or ARC

· Other ARC issues

Tell us what's going on

· Qobuz and Tidal work In Room desktop , Tidal works in ARC ,Qobuz is visible in ARC (playlists and albums) but fails steaming in ARC with the following indication: "problem communicating with Qobuz" . Have tried everything wifi box off/on, core server of/on , application reload , I phone off/on etc..

Tell us about your home network

Hi, I’m seeing the same ARC/Qobuz issue and I can now reproduce it consistently.

What works

  • Roon ARC connects to my Core successfully

  • Local files play in ARC

  • Qobuz plays normally in regular Roon / Roon Remote

What fails

  • Only Qobuz playback in ARC fails

  • ARC shows: “Problem communicating with Qobuz”

What I already tried

  • Logged out of Qobuz in Roon

  • Waited, restarted Roon Server, and logged back in

  • Reinstalled the ARC app

  • Tested on both Wi-Fi and 5G

  • Same result every time

Why I think this is not a local firewall/port issue

  • ARC can reach the Core

  • Local ARC playback works

  • The problem is isolated to the Qobuz-in-ARC path

Relevant log behavior
In the RoonServer logs I see successful Qobuz/API requests first, and then Roon marks Qobuz offline:

  • update qobuz location True => False

  • media availability ... Qobuz ... is offline

  • Unloading storage backend Qobuz Storage Library

I also see IPv4 connectivity succeeding for ARC, so this does not look like a basic remote-access failure.

Could you please confirm whether this matches the currently tracked ARC/Qobuz issue, and whether there is any workaround or fix timeline?

Thanks.

I can confirm this. Not working.

127

I’m not sure if this is related, but for the last year I have had the issue with ARC and Qobuz where I can play 1 track, then it has a communication error on any other track from Qobuz (but not local or Tidal) until I kill the phone app, clear data, and restart. I had an issue opened on this that was closed without resolution last year.

Unfortunately it still isn’t working for me either. Very frustrating.
